Specification of Letters Patent.

Application filed July 2, 1915. Serial No. 37,740.

To all whom it may concern Be it known that we, MARIE DE PALKOWSKA, a cltizen of the United States, and ALFRED BULLARD, a subject of the King of Great Britain, residing at New York, in the borough of Manhattan and State of New York, have invented or discovered certain new and useful Improvements in Exercising-Machines, of which improvements the following is a specification.

Our invention relates to exercising machines, and, more particularly, it is a machine of that sort which in its use involves the same bodily motions and the exercising of the same muscles as the operation of saw ing wood with a bucksaw on a sawhorse.

The invention is illustrated in the accompanying drawings of which- Figure 1 shows the exercising machine of our invention in perspective. In this view,

elevation of the sawhorse with the attached foot rests knocked down or collapsed, in the condition in which it will be shipped or laid aside when not in use. Fig. 3 is a view in perspective of the dummy saw log which is part of the machine, the several major parts of the saw log being shown] in this figure separated one from another for purposes of illustration. Fig. A is, a vertical longitudinal section through the dummy saw log. Fig. 5 is a view in plan of a portion of the dummy saw log, the portion at the left, Fig. 3, (part marked G in Fig.8 being removed). Fig. 6 is a view in perspective of the tray for containing the miniature facsimiles of lengths of cord wood which constitute the tally or registering counters of the machine.

Fig. 7 shows one of these miniature lengths.

of cord wood in perspective.

Referring first to Fig. 1, the machine will be seen to consist of a dummy sawhorse whose cross arms land 2 are pivoted one to another, of a dummy sawlog clamped between the upper ends of the arms 1 and 2, of

a dummy saw C movable in a transverse slot use, the users standing on these foot rests will more securely anchor the machine. The foot rests are collapslble and, as is particularly shown in Figs. 1 and 2, the sawhorse may be knocked down and the foot rests collapsed as a matter of convenience in shiparms 1 and 2, which connecting member may be tightened and loosened by a thumbscrew D. i

. Referring particularly to the dummy saw log, as it is particularly illustrated in Figs.

3 and 4, it will be seen to be formed preferably of an octagon shape for ready securing in the dummy sawhorse. It is provided with a transverse slot in which the dummy hand-saw is received, and in which the dummy hand-saw moves. As is best shown in Fig. 5, this dummy saw log is divided on an approximately horizontal medial plane,

and the upper portion of the log is again divided transversely to form the slot. The opposite walls of this slot are conveniently formed of two blocks or plates T and J of suitable material, as for example brake-lining or indurated fiber, which is durable and will not be injuriously heated by friction. The spacing of these two plates I and J from one another and therefor the effective width of the slot and the closeness of engagement of the two plates upon the opposite faces of the dummy saw introduced between them may be accomplished by having one of the two, for example the plate J (Fig. 4-), movable to and from the plate I. Fig. 4: shows plate J supportedin a suitable space within the dummy saw log by means of the slotted brackets 3. The slotted brackets allow the plate J to move toward and away from its fellow plate I. The plate J isborne on a stem N, through an intervening compres sion spring connection L, and the stem N is slotted and hung in the space within the log,

in the manner indicated at M. A screw extends through and though rotatable is longitudinally immovable in the end of the log. It is provided externally with a handle K. This screw at its inner end engages the stem N. Thus, by the turning ofthe handle K the position of plate J may be adjusted, the width of the slot controlled; the closeness of fit of the saw, the frictional resistance to the drawing of the saw to and fro in the slot, and the amount of muscular effort involved in using the machine, may be varied and ad.

justed as desired. The presence of the spring L (which ordinarily will be a spring of considerable resistance) allows plate J to adjust itself to inequalities in the thickness of the blade of the dummy saw, and affords a steadier resistance to the operation of the machine.

A block 0 is arranged in a suitable guideway in the body of the dummy saw log (see Fig. 3) and is movable in the direction of the length of the slot already described. Furthermore, the block 0 is itself provided witha slot which, when the parts are assembled, registers with and forms a continuationof the slot formed by the plates 1, J. When the parts are'assembled, and thesaw C is in place, and when the saw is moved to and fro in the slot, the engagement of the blade of the saw with the block 0 will cause it to move longitudinally in its runway, first in one direction and'then in the other.

- The ends of the runway of the block 0 are preferably provided with elastic bumpers P. e amount of traverse of block 0 is evidently far less than the extent of the stroke of the saw, but the frictional engagement of the saw with the block will carry it from one 7 Les expending.

end of the runway to the other, and when it abuts uponthe end of its runway, the

saw in its further traverse will slide in the slot in the block 0. And it will be seen that,

as the saw is drawn to and fro in the dummy saw log after the manner in which a handsaw is'operated in sawing a log of wood, the block 0 will reciprocate to and fro in its runway, oscillating in accordance with the reciprocating movement of the saw blade.

A tally device is provided,and the tally device operates in response to the shifting of the block 0, and thus a record is automatically kept of the number of strokes of the saw, and the users of the machine'have a check upon the amount of effort they are As shownin the drawings, a tray (Fig. 6) adapted to receive and sustain a number of miniature dummy sections of cord wood (Fig. 7) may be introduced within the dummy saw log in the manner indicated in Figs. 4 and 5. Anorifice W is formed through the lower part of the dummy log and through this orifice the dummy sections of cord wood escape. A suitably controlled escapement apparatus is arranged between the otherwise open lower end of the tray and the orifice W and this mechanism, whose action is controlled by the shifting of the block 0, determines the rate of the feed and escape of the small dummy sections of cord' wood. This escapement consists of a ninety-six required to release a single one of the miniadrum, in this case formed in two parts, V V, in the circumference of which drum is formed a recess of suitable size to receive these dummy lengths of cord wood, one section at a time. lVith each revolution of the drum, one section is carried from the lower end of the try to the escape orifice W. The drum V V is rotated by means of a ratchet T mounted rigidly on the axle of the drum, and a pawl S is provided for turning the ratchet T. Each reciprocation of the block 0 in its runway causes the pawl S to make its double stroke first forward and then back, operative connection being had through a bell-crank lever Q pivoted at R. A springimpelled pawl U prevents the retraction of the ratchet T on the backward stroke of the pawl S.

As particularly shown in Fig. 6, the edges of the tray Y may overhang, to provide for the feeding forward of the succession of dummy sections of cord wood in an orderly manner. A lock Z may be provided, serving, when in the full line position of Fig. 6, to hold the dummy sections of cord wood in place in the tray and, when turned by means of the connecting rod X to the dotted line position (Fig. 6) leaving the contained sections of cord wood free to escape to the drum V V, and at the same time by engaging block a a securing the tray in place. As particularly shown in Fig. 4, the tray when in place is inclined, to afford the proper feed of the dummy sections of cord wood to the escapement drum V V.

For every double stroke of the dummy saw the ratchet T will advance one tooth; if the ratchet be provided with forty-eight teeth, single strokes of the saw will be ture logs of the registering mechanism. Assuming that the amount of effort expended in drawing the saw ninety-six times back and forth in the slot in the dummy saw log is suflicient to saw through a six-inch log, the release of thirty-two logs will indicate the amount of work required to saw a quarter of a cord of wood. If then the tray Y be made of suitable size and initially charged with thirty-two miniature pieces of cord wood, the users of the machine may, in effect, cut a quarter of a cord of wood or any desired fraction thereof.
